Objectives: Early diagnosis, initiation of Alzheimer's disease (AD) therapy and programs that support care of persons with AD at home are recommended. The objective of this study was to assess the effect of early psychosocial intervention on delaying the institutionalization of persons with AD. We also assessed the influence of intervention on AD progression, behavioral symptoms, and health-related quality of life (HRQoL) in persons with AD and caregivers.Methods: Kuopio ALSOVA study, a prospective, randomized intervention study with a 3-year follow-up, was carried out at memory clinics. Home-dwelling persons with very mild or mild AD (n = 236) and AD-targeted therapy and their family caregivers (n = 236) were randomized to the intervention or control group (1:2). Psychosocial intervention including education, counseling, and social support was given during the first 2 years (16 days). The primary outcome was the cumulative risk (controlled for death) of institutionalization over 36 months. Secondary outcomes were adjusted mean changes from baseline in disease severity, cognition, daily activities, behavior, and HRQoL for persons with AD; and change in psychological distress, depression, and HRQoL for caregivers.Results: No differences were found in nursing home placement after the 36-month follow-up between intervention and control groups. No beneficial effects of the intervention were found on the secondary outcomes.Conclusions: The psychosocial intervention did not delay nursing home placement in persons with AD and had no effect on patient well-being, disease progression, or AD-related symptoms or caregiver well-being. Instead of automatically providing psychosocial intervention courses, individualized support programs may be more effective. [ABSTRACT FROM AUTHOR]

Background: We studied the suitability of The Consortium to Establish a Registry for Alzheimer's Disease Neuropsychological Battery (CERAD-NB) total score for monitoring Alzheimer's disease (AD) progression in early-diagnosed medicated patients. We also investigated possible differences in progression between patients with very mild or mild baseline AD.Methods: In this three-year follow-up of 115 ALSOVA study patients with clinical dementia ratings (CDR) of very mild (0.5) or mild (1) AD, we analyzed total CERAD-NB, Mini-Mental State Examination (MMSE), Neuropsychiatric Inventory (NPI), The Alzheimer's Disease Cooperative Study-Activities of Daily Living Inventory, and Clinical Dementia Rating Sum of Boxes scores. Correlations were identified with efficacy parameters.Results: Over three years, total CERAD-NB declined significantly in both groups. Annual change rates of total CERAD-NB were also significant. Total CERAD-NB revealed annual differences in cognition between study groups, while MMSE did not. Total CERAD-NB correlated well with other cognitive and global measures, but not with NPI. For almost two years, the CDR-0.5 group maintained a higher activities of daily living than the CDR-1 group exhibited at baseline. Furthermore, the CDR-0.5 group showed milder neuropsychiatric symptoms at the end of follow-up than the CDR-1 group showed at baseline.Conclusions: The CERAD total score is a suitable and sensitive follow-up tool in longitudinal AD trials. Cognition progression rates did not significantly differ between study groups; however, patients with very mild AD at baseline had milder neuropsychiatric symptoms after long-term follow-up. This emphasizes the importance of early diagnosis and assessment of neuropsychiatric symptoms at the diagnostic visit and during follow-up. [ABSTRACT FROM AUTHOR]

Background: Neuropsychiatric symptoms (NPS) are common manifestations of Alzheimer’ s disease (AD). Objective: To examine the prevalence and significance of NPS in very mild and mild AD patients with emphasis on their influence on the well-being of the patients and their caregivers. Methods: The participants were 240 patient-caregiver dyads who participated in a prospective, controlled rehabilitation study (ALSOVA). Three Quality of Life (QoL) instruments were used; generic 15D, disease-specific QoL-AD and Visual Analog Scale (VAS). The disease-specific QoL-AD was both selfrated and caregiver rated. Other scales used were Mini-Mental State Examination (MMSE), Clinical Dementia Rating (CDR), ADCS-ADL, Neuropsychiatric Inventory (NPI) and Beck Depression Inventory (BDI). Results: NPS were present in 76.5% of patients with very mild AD (CDR 0.5) and in 84.9% of patients with mild to moderate AD (CDR 1). The most frequent symptoms were apathy, depression, irritability, and agitation. The strongest predictor of self-reported QoL-AD scores was depressive symptoms whereas functional decline and presence of NPS predicted poor caregiver ratings of patients’ QoL. However, caregiver depression also influenced significantly their ratings. Conclusion: NPS are common even in the early stages of AD. NPS were significantly associated with caregiver assessment of the patient’s QoL but not with patients’ self-assessed QoL. Depression decreases QoL, but may remain unrecognized in AD patients, emphasizing the need for careful and structured assessment of NPS before deciding on the appropriate treatment.

Background: Cardiovascular disease incidence and mortality exhibit a winter peak and a summer trough, a fact that could have radiological manifestations. Purpose: To identify possible seasonal trends in the occurrence of thoracic vessel calcifications. Material and Methods: 505 male construction workers (aged 39–80 years) were each imaged once with chest spiral computed tomography (CT) during a 2-year period. Based on visual assessment of calcified plaques (0=no, 1=slight, 2=moderate, 3=extensive calcification), sum scores of atherosclerosis in coronary arteries, in the thoracic aorta, in the pre-cervical artery bases, and overall were constructed. The scores were regressed on the annual rank number of the CT day. Results: By using the cubic regression model, seasonal variation in calcified plaques in coronary arteries ( P=0.003), in pre-cervical artery origins ( P=0.015), and in the overall sum score ( P=0.004) was observed. The peak occurred in January–February and the nadir in August. Depending on the model, about 2–3% of the variation in atherosclerotic calcifications could be explained by the season of imaging. Conclusion: The observed seasonal trend in calcifications parallels with mortality reports. Seasonal variations should be considered in atherosclerosis treatment studies. Confirmatory studies using modern imaging technology are needed in different countries and geographical locations, preferably with repeat imaging of the same individuals. [ABSTRACT FROM AUTHOR]
